The Value of Graded Exercise Testing in Today's World

Central Michigan University, College of Health Professions, Mt Pleasant, Michigan, paul.visich{at}cmich.edu

With the continued high prevalence of coronary artery disease in our country, the need for diagnostic testing for myocardial ischemia will continue to be a high priority. Many advances have been made in the field of diagnostic testing for myocardial ischemia, but the combination of graded exercise testing (GXT) with 12-lead electrocardiogram (with or without nuclear perfusion imaging or echocardiography) continues to be the initial noninvasive test most accepted in the medical field. However, it is imperative that the patient is able and willing to give a good physical effort to increase the sensitivity in detecting disease. In addition to using GXT for diagnostic purposes, the GXT is also beneficial in respect to determining long-term prognosis, assessing therapeutic interventions, and assessing one's functional capacity for the purpose of determining appropriate and safe exercise training.

Key Words: graded exercise testing • diagnostic exercise testing • functional capacity • prognostic value • coronary artery disease
